Ellipsometric investigation of very thin films
Use of spectroscopic data obtained by investigation of a witness sample having a relatively thick dielectric on a surface thereof during deposition of a thin film onto the witness sample and onto a process sample having no, or a relatively thin dielectric on its surface, in characterizing thin film...
